If you've never traveled to Las Vegas, then you should know that there are actual rules and laws to follow while you're in the city. For you veterans, this will be a refresher course, but keep an open mind: You might just learn something new, because Vegas is forever changing.

Don't expect to find the same old Las Vegas.
Vegas is forever changing. In the last 10 years, over a dozen hotels have been demolished to make room for spectacular new ones.

Do plan to get a few great bargains.
The old establishments of Las Vegas are constantly trying to compete with the dancing fountains and the spit-fire volcanoes. So how are they still making it? Through the deep discounted dining experiences they offer visitors. In Vegas, you can still find a T-bone steak for $4.95. (You just have to know where to look.)

Don't come to Vegas during peak times.
Yes, everyone wants to get away during the weekend. But if you're planning on a weekend trip to Vegas, be ready to spend some extra money. Traveling to Vegas in the middle of the week, Christmas and when conventions are on hiatus, is a great way to enjoy the city without the crowds or the expense. Another great time to visit Vegas, if you can stand the heat, is during the mid-summer, when it's too hot for most visitors.

Do plan your Vegas vacation in advance.
Las Vegas is a large city with a lot to choose from -- casinos, spas, restaurants, shows. It can be overwhelming. To avoid delays once you arrive in Vegas, plan ahead. Map out what you want to see and do while in Sin City. Don't waste one minute. Once you land, hit the ground running.
